IMPROVEMENT IN REED-ORGANS.

Specification forming part of Letters Patent No. 137,350, dated April l,1873; application tiled February 8, 187 3.

To all lwhom it may concern:

Be it known that I, ANTON DREHER, of Cleveland, county of Cuyahoga andState ot' Chio, have invented certa-in Improvements in Melodeons, ofwhich the following is a specification:

This invention relates to an improved mode of constructing and arrangingreed-boards in melodeons or cabinet-organs; -and consists in making thevalve longer so as to cover another opening, communicating with an eXtraset of reeds or notes for a sub-bass or other accompaniment; also inarranging the subbass with the reeds standing upright, and having aninclosed communication with the valves aforesaid, consisting of taperingand concentrating channels, whereby the subbass is sounded with theother accompanying notes.

In the accompanying drawing, Figure l is a top or plan view of areed-board and action having my improvements, the top board of thechannels to sub-bass removed to show their construction. Fig. 2 is avertical section of the same.

A is a board on which are placed the reedboards. B is a reed-board;above is the action. Through the board A are the openings for thepassage of air, which are covered on the under side by the valves C.Thus far the construction does not differ from the ordinary.

My improvement consists in the extension ot the board A back and inplacing a reedboard, D, on it, standing on edge, in which the notes orreeds stand upright, and in making a series of air-conductors, E, tocommunicate with extra openings F in the board A. The conductors E aremade to concentrate so as to adapt them to the same scale as thereedboard B, for the notes in the board D, being larger, require morespace.

I make the valve C longer than usual to cover the extra openings F inthe board A, so that the same valves operate the additional set ofreeds. The air is drawn in at the top or ends of the reeds when thevalve is opened. I hinge the valves at the front ends.

By this arrangement one set of valves only is needed, making a simpleand economical construction for a sub-bass accompaniment.

Having described my invention, I claim- The combination and arrangementof the reed-board D, the conductors E, the extended valves C and theboard A, with the reed-board B, substantially as shown and described,and for the purpose set forth.

ANTON DREIIER.
